Strengthening microwave modification of structural elements of composite materials reinforced with synthetic fibers

Abstract

The strength characteristics of composite carbon and fiberglass plastics have been studied, after their modification by microwave radiation of various power input. It has been established that the microwave effect on the finally shaped object under various conditions of the parameters increases the ultimate bending stresses of the carbon fiber reinforced plastic by 47–53 %, the GRP by 60 %. At the same time, significant changes in the microstructure are noted, which are manifested in the increase in its homogeneity and density as the contact points of the matrix agglomerates and reinforcing fibers increase.
